Add new mime type "video/mp2t"
Since march 26, 2010 there is shared-mime-info 0.71-1ubuntu1 which recognizes the new mime type "video/mp2t" alias "mpeg 2 transport streams".
I successfully tested some mp2t streams in vlc. Since it does support these streams, it should be added to its mimetype list, in Linux under "/usr/share/applications/vlc.desktop".
To coordinate all changes for video/mp2t I filed https://bugs.launchpad.net/ubuntu/+source/desktop-file-utils/+bug/552162.
